My father in law has been smothering for quiet some time. He has a harder time breathing when laying on his right side. I noticed on his chart they had decided he has COPD. They have not told him that, but it was written in his chart. He has an appt with a pulmonologist tomorrow. I was wondering if anyone had any suggestions of what questions we should ask or what to expect. He has been a smoker for 40 years without any sickness at all. Thanks for any advice.
